What is this?

WATCH: Marijuana policy reform activists join The Morning Show to talk about Marc’s return from U.S. prison and Jodie’s run for federal politics.

TORONTO – Canada’s “Prince of Pot” is hoping to rally marijuana supporters by staging a welcome home party at Toronto’s Yonge-Dundas Square Thursday afternoon just days after his release from a U.S. prison.

B.C. marijuana activist Marc Emery posted an invite on his Facebook page Wednesday asking for people to show up between 3 to 5 p.m.

The 56-year-old Vancouver resident was extradited to Seattle in May 2010, when he pleaded guilty to selling marijuana seeds from Canada to American customers before serving his time in several U.S. corrections’ facilities.

When he was first arrested almost a decade ago, the Drug Enforcement Agency heralded his seizure as a “significant blow” to the legalization movement.

“For 45 years, we’ve got two million Canadians who have been arrested and given criminal records and suffered the duress of that kind of punishment and hundreds of thousands of people went to jail,” said Emery during an appearance on The Morning Show Thursday.

“It’s a peaceful, honest lifestyle choice. Why are we being punished?”
